ant-transfer checkall button should only control searhed items not all item list (search mode)

[wangtao0101]

Version

2.9.3

Environment

ant 2.9.3

Reproduction link

https://ant.design/components/transfer-cn/#components-transfer-demo-advanced

Steps to reproduce

chose 1 item
input some letter (do not search the chosed item)
click checkall button
click checkall button

What is expected?

the item chosen before should be chosen

What is actually happening?

no item is chosen

---

const holder = checkAll ? [] : filteredDataSource.map(item => item.key);
I think [] should include the items not showed in search mode

I don't think that we can find the right behavior. You can control the behavior with selectedKeys

用中文:))
I don't think that we can find the right behavior. 这个没错。
但是这个checkall按钮的行为是不一致的，这个有问题的
例如：搜索模式下 全选会选中当前搜索的条目，但是反选却反选了整个list，行为上至少要一致吧？

按我的理解，全选和反选，只要做到 WYSIWYG 就可以了，至于那些没展示出来的数据，是否该被选中或者反选，由业务代码决定。

Table 也是如此。

Make sure selection only affect filtered items.
